WATER-HEATER.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed November 16, 1911. Serial No. 660,582.

To all whom it may concern Be it known that I, FLAvIUs B. STIKER, acitizen of the United States, a. resident of Buffalo, in the county ofErie and State of New York, have invented certain new and usefulImprovements in Water Heaters; and I do hereby declare the following tobe a full, clear, and exact description of my invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and tofigures of reference marked thereon, which form part of thisspecification.

Like 'figures of reference refer to like parts.

My invention relates to the simpler form of water heaters as used incook stoves.

The objects of my invention are to provide 'a heating device which canbe readily cleaned out when the same becomes clogged with scale andother matter as accumulates during the use of a city water supply and toso form such a device, that it can be cheaply manufactured, while beingefiicient as an absorbentof heat units which escape the usual form ofheater made up of straight pipes and return bends. To accomplish theseobjects, I have devised a tubular metallic casting having a series offins integral therewith and having the bends thickened in a manner toform a boss at each bend, in which there is a hole adapted to receive ascrew-plug.

The details of construction of my device are illustrated in theaccompanying drawings and are hereinafter described and what I claim isset forth.

Figure 1, illustrates a plan of my device positioned in a stove. The topof the stove is shown broken away to expose said device to view. Fig. 2,is a sectional elevation of said devicetaken on the line X-X of Fig. 1.Fig. 3, shows a section of a heater using square tubes.

In the figures, in Fig. 1, 1 is a portion of a cook stove having thereintwo gas burners 2 and 3. Above said burners is positioned my device madeup of a tubular casting haw ing four parallel portions numbered respectively 4, 5, 6 and 7. The portions 4 and 5 communicate through the bend8, which is expanded into a boss 9' containing a screwplug 10. Theportion 5 communicates with the portion 6 through the bend 11 having aboss 12 and a screw-plug 13. Connecting the portions 6 and 7 is the bend14 which has a boss 15 containing a screw-plug 16. Across all four ofthe parallel portions 4, 5, 6 and 7 and integral therewith, are the fins17, 17, 17, a part of which with some of the parallel portions arebroken away to better show the burner 3 below the same. The extremitiesof the portions 4: and 7 are each expanded into the respective bosses 18and 19 adapted to receive the pipes 20 and 21.

In Fig. 2, parts similar to parts shown in Fig. 1 are similarly numbeid. In Fig. 3, a fin is markeo 22 as surroundmg two square tubes 23 and24 integral therewith. I

In operation, water coming from the pipe 20 finds its way into theportion 4, the bend S, the portion 5, the bend 11, the portion 6, thebend 14, and the portion 7, in succession into the pipe 21, the pipes 20and 21 being connected with a reservoir and circulating system notshown, but of the usual construction. During the circulation of Waterjust described, the heat produced by the burners 2 and 3 is absorbedthrough the exposed areas of the device including the greatly augmentedarea of the same in the fins.

In manufacturing these devices I find that the method of casting thesame entirely of one piece, exclusive of the said plugs, is verypractical and cheap, allowing me to compete in price with the ordinarycoil made up of straight pieces of pipe and return bends and otherfittings; while my device requires less fuel consumption to heat a givenquantity of water a given temperature and allows of easy cleanin whichis important in maintaining the e ciency of my device.

Other heat producers than those above re ferred to may be used inconnection with my device.

Having described my invention, I claim,

A water heating device comprising a tubular metallic casting having a,continuous bore in said casting and having a plurality of parallelportions with transverse fins 1n.-

tegral therewith, any two adjacent parallel portions bein in continuoustubular con- HQCMOH by means of a bend portion integral Li'ierewith, anda plug in screw-threaded engagcment with said bend portion, the free'ends of said casting being adapted for tight 1 pipe connectionssubst-antiallypas set forth. 10
